Description
FIELD OF THE INVENTION
This invention relates to an amusement ride, and more particularly
to an aerial amusement ride involving one or more riders being
conveyed through the air. The invention also relates to a method of
conducting an amusement ride.
BACKGROUND ART
There are a variety of amusement rides involving a rider or riders
being conveyed through the air in a manner somewhat simulating
flight. The rides can be on a relatively small scale for use in
playgrounds, or on a much larger scale for use in fair grounds and
theme parks.
One example of a ride involving conveyance of a rider through the
air is a swing. Swings can range from the simple variety as
commonly used in children's playgrounds to somewhat sophisticated
structures requiring mechanisms for raising riders into a launch
position from which they are released to swing through a curved
trajectory. Whilst swings can provide an entertaining ride, they
are generally rather limited in simulating flight, as typically
riders only swing back and forth along a curved trajectory.
Consequently, the rider achieves essentially the same ride each
time.
Another ride involving conveyance of a rider through the air is an
aerial carousel, where one or more riders are moved through a
generally circular path. Typically, an aerial carousel involves a
central column supporting a rotatable hub from which riders are
suspended to be conveyed through a circular path about the column,
thereby simulating flight. In a simple playground version of such
an amusement ride, chains extend from the rotatable hub and have
handles (typically configured as rings) attached to their free end
so that they can be grasped by the riders. With such rides, the
riders initially propel the hub by running around the column while
gripping the chains, and thereafter lift their feet from the ground
so as to move through the air, simulating flight. In more
sophisticated arrangements, the aerial carousels may incorporate
rider carriers (such as harnesses or carriages), and also a drive
system for driving the hub to cause the rider carriers to move
through a circular path around the central column. As with other
aerial amusement rides, the ride offered by an aerial carousel is
somewhat limited, as the riders merely move through a generally
circular path, achieving essentially the same ride each time.
It would be advantageous for there to be an aerial amusement ride
which can move a rider through the air but with provision for the
ride to be varied should that be desired in order to enhance the
sensation experienced by the rider.
DISCLOSURE OF THE INVENTION
According to a first aspect of the present invention there is
provided an amusement ride comprising a tower, a hub structure
supported on the tower for rotation with respect thereto and for
displacement therealong, a first drive means for rotating the hub
structure with respect to the tower, a second drive means for
displacing the hub structure along the tower, and a rider carrier
suspended from the hub structure to undergo motion in response to
movement of the hub structure with respect to the tower.
With this arrangement, the rider carrier can undergo motion
involving rotation around the tower and also displacement along the
tower to provide a change in elevation during the ride. The change
in elevation as the rider moves in a path around the tower can
enhance the sensation experienced during the ride.
Preferably, the rider carrier is suspended from the hub structure
by a flexible suspension link extending therebetween.
The flexible suspension link may comprise at least one flexible
line (such as a cable or chain), or a plurality of flexible lines
operating in conjunction.
The rider carrier may also be connected to the rotatable hub for
swivelling movement with respect thereto. Typically, such an
arrangement may be achieved by way of a swivel connection between
the flexible suspension link and the rotatable hub. Swivelling
movement can provide a further aspect to the sensation experienced
during the ride.
Typically, the swivelling movement comprises rotation about an axis
corresponding to the longitudinal extent of the flexible suspension
link.
Preferably, the amusement ride is adapted to accommodate a
plurality of riders at the same time. This may be achieved by the
provision of a plurality of rider carriers connected to the
rotatable hub in circumferentially spaced relation.
The or each rider carrier may be of any appropriate form such as,
for example, a harness structure to receive an support a rider or
several riders, or a carriage (such as a chair or pod) in which one
or more riders can be accommodated. A rider carrier which can
accommodate several riders is advantageous in that there is any
opportunity for riders to enjoy the thrill of riding together in a
common carrier.
In one arrangement, the rider carrier may be adapted to rotate
about an axis transverse to the longitudinal extent of the flexible
suspension link. In such an arrangement, the rider carrier may
comprise a capsule with seating for accommodating one or more
riders.
The rider carrier may be provided with a control device such as a
vane or other control surface for imparting rotational motion about
the rotational axis during movement of the rider carrier through
the air.
There may also be provision for a rider to selectively operate the
control device during the ride for providing variation to the
ride.
The tower may be a permanent installation or it may be demountable
to permit relocation. In another arrangement the tower may be
mounted on a trailer and be collapsible onto the trailer for
transportation.
The tower may, in one arrangement, comprise a column having a
plurality of column sections disposed in series and connected one
to another. The column sections may be detachably connected
together to facilitate demounting for relocation.
The tower may, in another arrangement, comprise a column having
extended and contracted conditions, the column comprising a
plurality of column sections moveable one relative to another for
moving the column between the extended and contracted conditions.
Typically, the column sections are disposed in a telescopic
arrangement.
With this arrangement, the column may be pivotally mounted on a
trailer whereby the contracted column is pivotally moveable between
an upright condition and a collapsed condition folded down onto the
trailer for transportation.
Preferably, the tower extends to a height of at least 30 meters.
Typically, the tower has a height of about 60 meters, and possibly
higher in certain applications.
The hub structure may comprise a plurality of outriggers, one
corresponding to each rider carrier, with the flexible suspension
link from which each rider carrier is suspended being connected to
a respective one of the outriggers. The connection between each
suspension flexible link and the respective outrigger may comprise
the swivel connection which permits swivelling movement of the
rider carrier referred to previously.
Where the tower is collapsible into a folded condition on a
trailer, the outriggers are preferably also collapsible into a
condition alongside the column.
Preferably the hub structure is rotatably supported on a ring
structure adapted for displacement along the tower while being
fixed against rotation with respect to the tower.
The first drive means may comprise a drive wheel and a motor for
rotating the drive wheel, the drive wheel being in driving
engagement with the hub structure, whereby rotation of the drive
wheel causes rotation of the hub structure relative to the ring
structure.
The second drive means is preferably, operable for selectively
causing the ring structure to undergo displacement with respect to
the tower.
The second drive means may comprise a cable and pulley system from
which the ring structure is suspended, and a winch mechanism, the
cable and pulley system comprising a pulley mounted on the tower
above the uppermost extent of displacement of the ring structure
and a cable having an end thereof connected to the ring structure,
the cable extending upwardly from the ring structure, around the
pulley and downwardly to be operable by the winch mechanism.
The cable is preferably connected to a counter-weight, the counter
weight being connected to the winch mechanism by way of a winch
cable.
Preferably, the cable and pulley system comprises a plurality of
cables and associated pulleys, each cable being connected at one
end to the ring structure, extending upwardly over its respective
pulley and downwardly to be operable by the winch mechanism.
Preferably, the counter-weight is accommodated within the open
interior of the column.
The design of the amusement ride according to the invention is
conducive to construction on a very large scale. As alluded to
earlier, it is envisaged that the tower may have a height in excess
of 60 meters in certain applications.

BEST MODE(S) FOR CARRYING OUT THE INVENTION
Referring to FIGS. 1 to 5 of the drawings, there is shown an aerial
amusement ride 10 according to a first embodiment. The aerial
amusement ride 10 involves conveyance of riders through the air in
a manner somewhat simulating flight at an elevation sufficiently
high to provide a thrilling sensation.
The aerial amusement ride 10 comprises a tower 11 anchored to the
ground 13. A support head 15 is mounted on the tower 13 and riders
17 are suspended from the support head 15 by way of flexible
suspension links 19 for conveyance through the air about the
tower.
The riders 17 are conveyed along a path which extends around the
tower 11, with the elevation of the riders being selectively
variable, as will be explained later.
The tower 11 comprises a base 21 and a column 23 mounted on the
base 21. The column 23 is of framework construction, comprising a
plurality of longitudinal elements 25 connected one to another by
lateral elements 26 which provide bracing, as best seen in FIG. 4
of the drawings. Each longitudinal elements 25 is of rectangular
cross-section and is oriented diagonally so that two adjacent faces
27, 28 thereof are outwardly facing, as best seen in FIG. 4.
While not shown in the drawings, the column 23 in this embodiment
comprises a plurality of column sections disposed in series one
upon another, with adjacent sections being detachably connected
together. With this arrangement, the height of the column, which is
a matter of design choice, can be established by using an
appropriate number of column sections. Additionally, the
arrangement facilitates erection of the column 23, as it is merely
necessary to fit one column section upon another, typically with
the assistance of a crane or other suitable load lifting
apparatus.
Because of the framework construction of the column 23, there is an
open space 29 defined within the column.
The support head 15 comprises an inner ring structure 31 adapted
for displacement along the column 23 while being fixed against
rotation with respect thereto, and an outer hub structure 33
rotatably supported on the inner ring structure 31.
The inner ring structure 31 is mounted on the column 23 for guided
rolling movement therealong. Specifically, the inner ring structure
31 comprises a peripheral frame 35 of generally circular
construction extending around the column 23. A plurality of sets of
rollers 37 are mounted on the frame 35 in two groups spaced one
with respect to the other in the longitudinal direction of the
column 23. The roller sets 37 in each group are circumferentially
spaced around the column 23, with each roller set 37 corresponding
to one of the longitudinal elements 25 of the column 23. Each
roller set 37 comprises two rollers 39 positioned for rolling
engagement against respective outer adjacent faces 27, 28 of the
corresponding longitudinal element 25, as best seen in FIG. 4. This
is achieved by supporting the rollers 39 in each set with their
axis of rotation substantially at 90 degrees with respect to each
other. With this arrangement, the respective longitudinal element
25 defines a track and the faces 27, 28 define two track surfaces,
with each roller 39 in the roller set 37 engaging a respective one
of the track surfaces. The orientation of the two rollers 39 in
each roller set 37 and also the track surfaces, ensures that the
ring structure 31 is supported for guided rolling movement along
the column 23 while being restrained against rotation around the
column.
The hub structure 33 comprises a hub frame 41 of generally circular
construction rotatably mounted on the ring structure 31, and a
plurality of outriggers 43 extending from the hub frame 41.
A canopy covers the hub structure 33. The canopy 45 is shown partly
cut-away in FIGS. 2 and 3.
A first drive means 51 is provided for rotating the hub structure
33 with respect to the ring structure 31, thereby rotating the hub
structure 33 with respect to the column 23. The drive means 51
comprises an electric motor 53 and a drive wheel 55 drivingly
connected to the motor 53. The electric motor 53 is supported on
the inner ring structure 31 and the drive wheel 55 is in driving
engagement with a drive ring 57 mounted on the hub frame 41. In
this embodiment, the drive wheel 55 comprises a rubber wheel which
is adapted to frictionally engage the drive ring 57, whereby
rotational torque applied to the drive wheel 55 is transmitted to
the hub structure 33 through frictional engagement between the
drive wheel 55 and the drive ring 57 mounted on the hub frame
41.
A second drive means 61 is provided for displacing the support head
15, and thus the hub structure 33 forming part thereof, along the
column 23. The second drive means 61 comprises a cable and pulley
system 63 from which the support head 15 is suspended, together
with a counter-weight 65 and a winch mechanism 67.
The cable and pulley system 63 comprises a plurality of cables 71
(there being four such cables in this embodiment). One end of each
cable 71 is attached to the ring structure 31 of the support head
15 and the other end of each cable is connected to the
counter-weight 65. Each cable 71 passes over a respective pulley 73
mounted on the column 23 at a location above the uppermost extent
of displacement of the support head 15. From the connection to the
support head 15, each cable 71 passes upwardly to be routed around
its respective pulley 73 and then extends downwardly to the
counter-weight 65. The counter-weight 65 is connected to the winch
mechanism 67 by way of a winch cable 75. The winch mechanism 67
incorporates a winch drum 68 about which the winch cable 75 can be
wound and unwound.
The counter-weight 65 is selected such that the support head 15 can
travel downwardly under the influence of gravity, with its weight
partly being compensated by the counter-weight 65. The rate of
decent of the support means 15 on the column 23 is controlled by
the rate at which the winch cable 75 is unwound from the winch
mechanism 67. The winch mechanism 67 incorporates a disc brake (not
shown) operation of which can regulate the rate at which the winch
cable 75 is unwound.
Operation of the winch mechanism 67 to wind the winch cable 75
about the winch drum pulls the counter-weight 65 downwardly thereby
pulling the support head 15 upwardly through the cable and pulley
system 63.
The counter-weight 65 is accommodated within the open space 29
within the framework defining the column 23. This provides for
compactness of construction and also allows the longitudinal
elements 25 within the column 23 to be used for the purposes of
guiding movement of the counter-weight as it moves upwardly and
downwardly corresponding to displacement of the support head 15. To
this end, the periphery of the counter-weight 65 is configured so
that the counter-weight can be accommodated within the open space
29 for guided movement therealong by the longitudinal elements
25.
Compactness of construction is further achieved by positioning the
winch mechanism 67 on the base 21 and also within the open space 29
defined by the column 23.
Accordingly, both the counter-weight 65 and the winch mechanism 67
are accommodated within the confines of the tower 13.
The riders 17 are accommodated in rider carriers 81 which are
suspended from the outriggers 43 by way of the flexible suspension
links 19. Each flexible suspension link 19 comprises a flexible
line 83 which in this embodiment is in the form of a cable or
chain, with one end of the flexible line 83 being connected to a
respective one of the outriggers 43 and the other end of the
flexible link 83 being connected to a respective rider carrier
81.
In this embodiment, the rider carriers 81 comprise harness
structures in which the riders 17 can be accommodated. Other types
of rider carriers are of course possible, including carriages in
the form of seats or pods accommodating one or more riders.
While the harness structures defining the rider carriers 81 in the
embodiment each accommodate a single rider, it is possible to
utilise a tandem or other multiple harness in which several riders
may engage in the thrill of riding together in a common
carrier.
The connection between each suspension line 83 and its respective
rider carrier 81 may incorporate a swivel to permit the rider to
twist around an axis corresponding to the longitudinal extent of
the suspension line. In this way, the rider has the option of
twisting or otherwise manipulating his or her body around in order
to provide further variety to the ride and thus enhance the
sensation experienced during the ride.
Operation of the ride according to the first embodiment will now be
described. The ride commences with the riders 17 at ground level or
at an appropriate loading station near ground level, as shown in
FIG. 5a. The support head 15 is lowered by operating the winch
mechanism 67 to unwind the winch cable 75 from the winch drum 68.
Once the support head 15 has been lowered sufficiently so that the
riders 17 can be accommodated in the rider carriers 81 and
appropriately secured in position, the winch mechanism 67 is
operated to wind in the winch cable 75, thereby pulling the
counter-weight 65 downwardly and thus causing the support head 15
to move upwardly along the column 23, as illustrated in FIG. 5b.
During the upward ascent, and once the riders 17 are sufficiently
clear of the ground or loading station as well as any other
obstacles, the first drive means 51 can be actuated so as to cause
the hub structure 33 to rotate about the column 23. This causes the
riders 17 to swing outwardly on the suspension lines 83 and move
through a somewhat circular path around the column 23, also as
shown in FIG. 5b. During the ride, the support head 15 can be
lowered as illustrated in FIG. 5c and raised as illustrated in FIG.
5d in order to change the elevation of the riders as they move
through the circular path about the column 23. The speed of
rotation of the hub structure 23 can also be varied if desired to
provide variation to the ride characteristics. Typically, the hub
structure 33 rotates at about 10 rpm in this embodiment. The
displacement of the support head involving movement upwardly and
downwardly during the ride may be at speeds up to about 5 m/s.
During the ride, the support head 15 can be lowered at a rate
faster than the riders 17, thus providing situations where the
riders 17 may be higher than the points at which they are attached
to the ride.
The variation in elevation during the revolving motion of the
riders provides an exciting ride, particularly when regard is had
to the significant height at which the ride is conducted. Further
variation is available to the riders 17 during the ride through
swivelling movement at the connection between the suspension line
83 and the rider carrier 81. To complete the ride, the support head
15 is lowered so as to return the riders 17 to the ground or
loading platform.
Referring now to FIGS. 6 to 10 of the drawings, there is shown an
amusement ride 100 according to a second embodiment. The amusement
ride 100 is similar in many respects to the amusement ride 10
according to the first embodiment and corresponding reference
numerals are used to identify similar parts.
The tower 11 comprises a base 21 and a column 23, as was the case
in the first embodiment. In this embodiment, the base 21 comprises
a plurality of legs 101 extending radially outwardly, with
anchoring pads 103 provided on the outer ends of the legs 101 for
engagement with the ground 13. The base 21 also incorporates a
station 105 at which riders are loaded onto, and unloaded from, the
ride. The station 105 comprises a platform 107 which extends around
the tower 11 and which is accessible by way of stairs 109.
The base 21 also incorporates a portion 111 extending downwardly,
accommodated within a hole 113 formed in the ground.
The column 23 is of framework construction and is formed in column
sections 115 connected one to another at junctions 117.
In this embodiment, the rider carriers 81 comprise chair structures
119 which may be fitted with an appropriate restraint system for
the purposes of restraining riders in position during operation of
the ride.
The flexible suspension link 19 suspending each rider carrier 81 to
a respective outrigger 43 comprises a pair of flexible lines 121
such as cables or chains. The flexible lines 121 are connected at
their upper end to a crossbar 123 which in turn is connected to the
respective outrigger 41 by way of swivel connection 125.
Operation of the amusement ride 100 according to the second
embodiment is similar to that of amusement ride 10 according to the
first embodiment, with the ride commencing with the support head 15
lowered into a position at which riders can enter the chairs 119 at
the station 105, as shown in FIG. 8 of the drawings. The support
head is then raised into an operative condition and rotated and
displaced in a similar fashion to the first embodiment.
In this embodiment, all chairs 119 are accommodated at the station
105 at the same time. Thus, riders enter and leave the various
chairs 119 at the station at the same time.
In an alternative arrangement, the station may be at a specific
location, with the chairs 119 moving sequentially into and out of
the station. With such an arrangement, the drive means for rotating
the support head 15 can be utilised to rotate the chairs in an
indexing fashion, with the chairs moving into and out of the
station one after another. This can be advantageous in that the
ride operator would than be in a better position to exercise
control over the loading and unloading process, particularly with
regard to the manner in which riders enter and leave each
chair.
The amusement ride 100 according to the second embodiment has been
designed so that it is conducive to construction on a very large
scale. Indeed, the tower 11 is approximately 60 meters in height
and the diameter of the rotatable support head 15 is approximately
18 meters. The enormous size of the amusement device ensures that
the riders are exposed to an extreme height during the ride,
thereby enhancing the sensation experienced during the ride.
Referring now to FIGS. 11 and 12, there is shown a rider carrier 81
and a flexible suspension link 19 for an amusement ride according
to a third embodiment. The flexible suspension link 19 comprises
two lines 131 suspended from a cross member 133 connected by pivot
connection 135 to outrigger 43. The pivot connection 135
facilitates outward swinging motion of the rider carrier. The rider
carrier 81 comprises a capsule 141 in which several riders can be
accommodated. The capsule 141 incorporates seating 143 for riders
in the capsule. The capsule 141 is rotatable supported between a
two trunnions 145, with each trunnion 145 being connected to one of
the lines 131. With this arrangement, the trunnions 145 define a
rotational axis about which the capsule 141 can rotate. The capsule
141 has an outer periphery fitted with control devices 147 in the
form of vanes, as shown in FIG. 12. The vanes 147 cause the capsule
141 to rotate about the rotational axis upon movement of the
capsule through the air with rotation of the hub structure 33. The
angle of attack of the vanes 147 determines the speed of rotation
of the capsule. The direction of rotation may be altered by
altering the attitude of the vanes; that is, by facing them in an
opposite direction relative to the rotational axis of the capsule.
There may be provision for a rider to selectively move one or both
of the vanes for the purposes of controlling the direction and
speed of rotation of the capsule. The control may be achieved by
way of a lever mechanism located within the capsule 141 and
operatively connected to one or both vanes. This presents the rider
with an opportunity to control his or her own ride, thereby
providing variation to the ride and further enhancing the sensation
experienced on the ride.
There may also be provision for locking the capsule 141 against
rotation during the ride. The locking mechanism may be controlled
by the ride operator who may provide the rider with the choice as
to whether or not the rotational function will be employed during
the ride.
The rotatable capsule provides a further axis of rotation during
the ride, providing variety and thus a generally more exciting
ride. The feature may also be conducive to repeat business, as
riders may wish to develop their skills over time in controlling
the ride.
In the embodiments previously described, the amusement rides are
not readily transportable from one location to another. In
particular, each embodiment has the tower thereof anchored to the
ground. This is appropriate for amusement rides intended to be
permanent installations, such as for instance in amusement parks.
However, there is a need for an amusement ride that can be
transported from one location to another according to demands and
opportunities presented for the amusement ride. Such an amusement
ride would be particularly advantageous for use at temporary
amusement sites, such as those created in public open space,
fairgrounds, parklands, and parking areas and other spaces at
shopping centres.
An amusement ride can be provided with mobility by appropriate
design to facilitate ready disassembly into a condition for road
transport such as by incorporating the ride onto a transport
vehicle such as a trailer. However, many jurisdictions only allow
one trailer and so it would be advantageous for the amusement ride
to be incorporated on a single trailer. The fourth embodiment, as
shown in FIGS. 13 to 28, provides such an amusement ride.
Referring now to FIGS. 13 to 29, there is shown a mobile amusement
ride 150 incorporated on a trailer 165. The amusement ride 150
comprises a tower 151 and a support head 153 mounted on the tower
151. Riders 155 can be suspended from the support head 153 by way
of flexible suspension links 157 such as cables for conveyance
through the air about the tower. The riders 155 are carried in
rider carriers 158 attached to the ends of the flexible suspension
links 157. In this embodiment, the rider carriers 158 comprise
harnesses. However, the rider carriers may take any other
appropriate form such as seat structures and gondolas.
The tower 151 comprises a column 161 mounted on a base 163
incorporated into the trailer 165.
The trailer 165 is of conventional construction, involving a frame
structure 167 carried on wheels 169. The frame structure 167 has
facility at the forward end thereof for attachment to a towing
vehicle. The frame structure 167 incorporates a stabiliser system
170 comprising retractable outrigger legs 171, as best seen in FIG.
20, for engagement with the ground 172 to stabilise the trailer 165
when the amusement ride is operational.
The amusement ride 150 is selectively moveable between an
operational condition and a collapsed condition on the trailer 165
for transport. When the amusement ride 150 is in the operational
condition, the column 161 occupies an upright condition, extending
upwardly from the base 163, as shown in FIG. 13.
The column 161 is of telescopic construction, comprising a
plurality of column sections 180 moveable one with respect to
another to provide extended and contracted conditions for the
column. In this embodiment, there are three column sections 180,
being a first column section 181, a second column section 182 and a
third column section 183. The first column section 181 is lowermost
and the third column section 183 is uppermost, with the second
column section 182 being intermediate the other two column
sections. The first section 181 receives the intermediate section
182 which in turn receives the upper section 183 as the column 161
moves from the extended condition into the contracted condition. In
the contracted condition of the column 161, the various column
sections 180 are in a nested arrangement.
Cable and pulley system 186 is provided for controlling extension
and contraction of the column 161. The system 186 operates in
conjunction with winch 188 mounted on the trailer, as shown in FIG.
19.
In this embodiment, the column 161 is of rectangular cross-section,
comprising four longitudinal outer sides 162. The column sections
180 have outer faces 184 which co-operate to form the four column
sides 162. With the column 161 being of telescopic construction,
the various column sections 180 necessarily have different lateral
dimensions and consequently there are two steps 185, 187 present in
the outer sides 162 at the locations of overlap between the
respective column sections 180. In this embodiment, the lateral
dimensions of each column comprise width and depth, represented by
the spacing between opposed sides thereof.
The column 161 is hingedly mounted at hinge 189 to the base 163 for
pivotal movement into the collapsed condition whereby the
contracted column is folded down into a compact arrangement on the
trailer, 165 as best seen in FIG. 14 of the drawings.
A power device in the form of a hydraulic ram 191 is provided for
pivotally moving the contracted column 161 about the hinge 189
between the collapsed and upright conditions.
The support head 153 comprises an inner ring structure 193 adapted
for displacement along the column 161 while being fixed against
rotation with respect thereto, and an outer hub structure 195
rotatably supported on the ring structure 193, as was the case with
earlier embodiments.
As is also the case with earlier embodiments, the ring structure
193 is mounted on the column 161 for guided rolling movement
therealong. In the present embodiment, however, there is a need for
the inner ring structure 193 to accommodate the different lateral
dimensions that exist along the column 161 as a result of the
telescopic construction of the column, as well as the resultant
steps 185, 187. For this purpose, the ring structure 193 is
provided with four roller assemblies 200, one corresponding to each
of the four longitudinal outer sides 162 of the column 161, with
each roller assembly 200 adapted for rolling movement along one of
the respective column sides.
The roller assemblies 200 are each mounted on a frame 201 forming
part of the ring structure 193.
Each roller assembly 200 comprises two sets of rollers 210 mounted
on the frame 201 spaced one with respect to the other in the
longitudinal direction of the column 161, thereby providing two
groups 205, 207.
Each roller set 210 comprises three rollers positioned for rolling
engagement against a respective outer side 162 of the column 161.
More particularly, each roller set 210 comprises a first roller
211, a second roller 212 and a third roller 213. The first roller
211 is provided for rolling engagement along the respective outer
face 184 of the first column section 181, the second roller 212 is
provided for rolling engagement along the respective outer face 184
of the second column section 182, and the third roller 213 is
provided for rolling engagement along the respective outer column
face 184 of the third column section 183.
It is necessary for each roller set 210 to accommodate the
different lateral dimensions of the three column sections 181, 182
and 183. For this purpose, the second roller 212 in each roller set
210 is retractable from an operating condition in which it can
rollingly engage the second column section 182 to guide movement of
the ring structure 193 therealong. The second roller 212 is
retractable into a retracted condition which accommodates the first
column section 181. In the retracted condition, the second roller
212 rolls along the first column section 181, and in doing so
interacts with that column section to provide some guidance. The
third roller 213 is also retractable from an operating condition in
which it can rollingly engage the third column section 183 to guide
movement of the ring structure 193 therealong. The third roller 213
has two retracted conditions, being an intermediate retracted
condition accommodating the second column section 182 and a fully
retracted condition accommodating the first column section 181. In
each of the intermediate retracted condition, the third roller 213
rolls along the second column section 182 in a floating fashion
without the interaction necessarily providing any effective
guidance, However, in the fully retracted condition the third
roller 213 can interact with the first column section 181 to
provide some guidance.
The second and third rollers 212, 213 are each biased towards its
respective operating condition, and also is moveable away from that
condition towards the relevant retracted condition upon contact
with the step 185, 187 at the junction between adjacent column
sections during descent of the support head 153 along the column
161.
Each first roller 211 is supported on a rigid arm 221, and each of
the second and third rollers 212, 213 are supported on a swing arm.
Specifically, each second roller 212 is supported on swing arm 222
and each third roller 213 is supported on swing arm 223. The swing
arms 222 and 223 are pivotally supported on the frame 201 for
pivotal movement between the operating and retracted
conditions.
The swing arms 222, 223 are oriented so that the rollers supported
thereon are biased into their operating conditions under the
influence of gravity.
A stop 225 is associated with each swing arm 222, 223 to limit the
extent of retraction of the swing arm. With this arrangement, the
stop 225 associated with swing arm 222 determines the retracted
condition thereof, and the stop 225 associated with the third swing
arm 223 determines the fully retracted condition thereof.
The manner of operation of the roller assemblies is best seen with
reference to FIGS. 24 to 28 of the drawings, where two opposed
roller assemblies 200 are shown in engagement with the column 161.
In the drawings, only two roller assemblies 200 are shown, being
the roller assemblies in engagement with two opposed outer sides
162a and 162b of the column. It will be appreciated that there are
a further two roller assemblies which are not shown in engagement
with the other two opposed faces.
As is illustrated in FIG. 24, each of the rollers is in contact
with the respective outer side 162 of the column 161. The first
rollers 211 are in contact with the outer side 162 for guiding
movement therealong by virtue of their position as determined by
the rigid arms 221. The second rollers 212 are in rolling contact
with the outer side 162 for guiding movement therealong by virtue
of being in their retracted conditions as determined by their
respective stops 225. Similarly, the third rollers 213 are in
rolling contact with the outer side 162 for guiding movement
therealong also by virtue of their fully retracted conditions as
determined by their respective stops 225.
As the roller assemblies 200 move across the step 185 between the
first and second column sections 181, 182, the second rollers 212
move under the influence of gravity into their operating
conditions, and the third roller assemblies 213 move into their
intermediate retracted conditions. At this stage, guiding support
is provided by the trailing group 207 of rollers being in
engagement with the first column section 181, and the second
rollers 212 within the leading group 205 being in guiding
engagement with the second column section 182, as shown in FIG. 25.
While the third rollers 213 within the leading group 205 are in
contact with the second column section 182, it is only a floating
engagement by virtue of the influence of gravity; they do not
provide any significant guiding support.
Continued upward movement results in both rollers groups 205, 207
within the roller assemblies 200 being in contact with the second
column section 182, as shown in FIG. 26. At this stage, guiding
support is provided by the second rollers 212. The first rollers
211 are entirely clear of the second column section 182, and the
third rollers 213 are merely in floating engagement with the
columns section.
As the roller assemblies 200 continue their upward movement they
encounter the second step 187, as shown in FIG. 27 of the drawings.
At this stage, the third rollers 213 in the leading group 205 have
moved into their operating conditions for rolling engagement with
the third column section 183, with the result that guiding movement
is provided by those rollers in the leading group 205 as well as
the second rollers 212 in the trailing group 207.
Further continued upward movement of the roller assemblies 200
results in all of the third rollers 213 being in rolling engagement
with the third column section 183 for guiding movement therealong,
as shown in FIG. 28.
A similar sequence operates upon reverse movement of the roller
assemblies 200 upon descent of the support head 150. As the roller
assemblies 200 encounter the step 187 during the descent, the
second rollers 212 move into their operating conditions for
engagement with the second column section 182 and the third rollers
213 are deflected into their intermediate retracted condition by
contact with the step. Similarly, upon encountering the step 185,
the first rollers 211 move into engagement with the first column
section 181, and the second rollers 212 are deflected into their
retracted conditions for rolling engagement with the first column
section 181. Similarly, the third rollers 213 are deflected from
their intermediate retracted condition into their fully retracted
condition, also for rolling engagement with the first column
section 181.
A first drive means (not shown) is provided for rotating the hub
structure 195 with respect to the ring structure 193, thereby
rotating the hub structure with respect to the column 161. The
drive means is of similar construction, and also operates in a
similar way, to first drive means 51 in earlier embodiment and so
will not be described further.
A second drive means 231 is provided for displacing the support
head 153, and thus the hub structure 195 forming part thereof,
along the column 161. The second drive means 231 comprises a cable
and pulley system 233 from which the support head 153 is suspended,
together with a counter-weight 235 and a winch mechanism 237. The
winch mechanism 237 is mounted on the trailer 165.
The cable and pulley system 233 comprises a plurality of cables 239
(there being four such cables in this embodiment one corresponding
to each side of the column). One end of each cable 239 is attached
to the corresponding frame 201 of the ring structure 193 of the
support head 153, and the other end of each cable is connected to
the counter-weight 235. Each cable 239 passes over a respective
pulley system 241 mounted on the column 161 at a location above the
uppermost extent of displacement of the support head 153. From the
connection to the support head 153, each cable 239 passes upwardly
to be routed around its respective pulley system 241 and then
extends downwardly to the counter-weight 235. The counter-weight
235 is connected to the winch mechanism 237 by way of a pair winch
cables 245. The winch cables 239 are provided as a pair for safety
purposes. The winch mechanism 237 incorporates a winch drum 247
about which the winch cables 245 can be wound and unwound.
The counter-weight 235 is selected such that the support head 153
can travel downwardly under the influence of gravity, with its
weight being partly compensated by the counter-weight 235. The rate
of decent of the support means 153 on the column 161 is controlled
by the rate at which the winch cables 245 are unwound from the
winch mechanism 237. The winch mechanism 67 incorporates a disc
brake (not shown) operation of which can regulate the rate at which
the winch cable 245 are unwound.
The counter-weight 235 is accommodated within the open interior 251
in the column 161. This provides for compactness of
construction.
Additionally, a safety brake 249 is associated with each cable 239
in the cable and pulley system 233.
Operation of the winch mechanism 237 to wind the winch cables 245
about the winch drum 247 pulls the counter-weight 235 downwardly,
thereby pulling the support head 153 upwardly through the cable and
pulley system 233.
The outer hub structure 195 comprises an inner hub portion 261
rotatably supported on the inner ring structure 93, and a plurality
of outriggers 263 extending outwardly from the inner hub portion
261.
Each outrigger 263 comprises a rigid outrigger arm 265 configured
as a pair of rigid elements 267, as shown in FIG. 22. The outrigger
arm 265 is pivotally connected at its inner end by hinge 268 to the
inner hub portion 261.
Each outrigger 263 further comprises a flexible tensile element 271
configured as two cables 273 each attached at one end 275 to the
inner hub portion 261 and attached at 277 to the outer end of the
rigid outrigger arm 265.
With this arrangement, the outriggers 263 are foldable between an
operating condition extending outwardly from the inner hub portions
261 for supporting riders (as shown in FIG. 13) and a collapsed
condition (as shown in FIGS. 14 and 15).
Each outrigger 263 is moveable from the operating condition to the
collapsed condition by pivotal movement of the rigid outrigger arms
265 about the hinges 268. In the collapsed condition, the rigid
outrigger arms 265 are folded upwardly to lie alongside the column
161. The flexible nature of the cables 273 facilitate folding
movement of the outrigger arms 265. The outriggers 263 are returned
to the operating condition by folding the rigid outrigger arms 265
outwardly about the hinge axis 268 until the cables 273 are under
tension, thereby supporting the rigid outrigger arms in the
extended condition.
A control mechanism (not shown) is provided for moving the
outrigger portion 263 between the folded and extended
conditions.
Folding of the outriggers 263 provides the support head 153 with
the feature of collapsibility.
A cradle 250 is provided for accommodating the support head 153 in
its lowermost position on the column 161. The support head 153 is
rested on the cradle 250 before the support head 153 is
collapsed.
Once erected, the amusement ride 150 according to this embodiment
operates in a generally similar way to the amusement ride 10 of the
first embodiment. However, the amusement ride 150 is mobile and
that aspect of the ride will now be described.
As explained previously, the amusement ride 150 has a collapsed
condition for transport, as illustrated in FIG. 14. In the
collapsed condition, the amusement ride 150 is accommodated on the
trailer 165 which can be towed to a site at which the amusement
ride is to be erected. Upon arrival at the site, the stabilizer
system 170 is deployed, involving extension of the outrigger legs
171 outwardly for engagement with the ground, as illustrated in
FIG. 20. Once the trailer 165 has been stabilized, the column 161
is pivoted from the collapsed condition into the upright condition
by operation of the hydraulic ram 191. At this stage, the amusement
ride 150 is in the condition illustrated in FIG. 15. It will be
noted that the column 161 is still in its contracted condition and
the support head 153 is also in its collapsed condition. The
support head 153 is then moved from the collapsed condition to the
operating condition, involving pivotal movement of the outriggers
263 outwardly into the extended condition, as shown in FIG. 16. The
column 161 is then moved from the contracted condition into the
extended condition, as shown in FIG. 17. Other procedures involved
in assembly of the amusement ride 150 for use can then be
completed.
As alluded to previously, the ride 150 operates in a similar
fashion to the ride 10 according to the first embodiment, and so
will not require further description, apart from noting that the
roller assemblies 200 operate in the manner described in relation
to FIGS. 24 to 28 in order to accommodate the various lateral
dimensions of the column 161.
When the amusement ride 150 is to be removed from site, it is
disassembled in a procedure which is essentially a reverse of the
assembly procedure, returning the ride 150 to the collapsed
condition, as shown in FIG. 14, where it is accommodate on the
trailer 165 for transport to another location.
From the foregoing, it is evident that the present invention
provides an amusement ride involving one or more riders being
conveyed through the air but with the possibility of sufficient
variation to provide an exciting ride conducive to riders returning
for further rides.
The amusement ride according to the invention can be constructed on
a large scale such that the riders are elevated to a height that in
itself provides excitement. The amusement ride is of a design which
is conducive to construction on such a large scale. This is
achievable even in the mobile amusement ride which is collapsible
onto a trailer for transport, owing to the telescopic nature of the
column and the ability of the support head to move along the
telescopic column in a manner accommodating variations in lateral
dimensions of the column.
The ride also incorporates a simple yet highly effective
arrangement for driving the support head both rotationally for
moving the riders around through the air, and also linearly for
varying the elevation of the riders during the ride as well as
raising and lowering the riders with respect to the ground or a
station at which the riders embark upon, and disembark from, the
ride.
Modifications and improvements may be made without departing from
the spirit of the invention.
Throughout the specification, unless the context requires
otherwise, the word "comprise" or variations such as "comprises" or
"comprising", will be understood to imply the inclusion of a stated
integer or group of integers but not the exclusion of any other
integer or group of integers.
